Application filed December This invention relates to improvements in the Construction and method of making fire cra'ckers.

One of the objects of this invention, is

to provide a fire Cracker entirely devoid of end plugs and the like, the explosive matter being folded within a box like container and securely located within a tapered tubular portion.

Further objects of this invention will appear from the disclosure in the single sheet of drawings herewith made a part of this application and in the 'following detaled description.

In the drawings,

i Fig. l illustrates a vertical sectional View of the fire cracker showing the explosive matter and fuse connected thereto within the tapered tubular portion.

Fig. 2 represents a perspective View of the box like container for the explosive in partly folded condition.

Fig. 3 illustrates a perspective View ,of Fig. 2, disclosing 'the box like containerfor 25 the explosive folded to a greater degree than disclosed in Fig. 2.

-Figs 4 and 5 represent perspective Views of the box like container for the explosive in further stages of folding.

Numeral 1 designates a tapered tubular portion adapted to hold securely therein, at

a point midway between its ends, 2 and 3, a

bag or package with explosive matter 4, the bag 5 being preferably formed from a sin- 35 gle sheet of suitable material having a slot or slit 6 properly located along one edge 7 'thereof.

The bag 5 in its folded and completed con:

diton as disclosed in Fig. 5, will obviously include two distinct and separate portions 8 and 9 adapted to fold up from one end of the explosive bag container, the portion 9 being particularly adap'ted to fold up `within the outer layer of the bag while the portion 8 will fold Upward along the exterior portion of the bag, thereof,-forming an end piece which will aid materially in hold-- ing the explosive bag securely within the tapered tubular portion l. This isbrought about from the fact thatthe folded end por- 8, 1925. Serial No. 74,066.

tion 8 has a dstinct tendency to bear outwardly toward the inside periphery of the tape'red tubular portion l, thereby increas ing the frictional resistance within the tu bular portion l.

The explosive material 4 is placed within the bag 5, the upper portion of which is sealedin a suitable manner by ,means of cordslO or otherwise, after inserting addi-` tional explosive material 4, the ends of a fuse ll, the fuse ll being so positioned in connection with the explosive material 4 that the looped portion 12 is located at a suitable distance beyond one end of the tapered tubular section 1, thereby forming a fuse having a considerably higher degree of efficiency than the fuse at present commonly used in the manufacture of 'fire crackers. In lightin or setting the looped 'end of the fuse as described in this application, it is obvious, that two lighted end portions will find their way into the explosive matter or it may be that one of the ends will become extinguished while the other end will perform the required duty.

This invention provides a fire Cracker having eficient means 'for securely folding the explosive matter and its container within a tapered tubular portion, which portion 1, may be made of any suitable material, the

tapered eifect making it possible to more` securely bind the explosive matter in its proper position Somewhere between the two ends of the tubular tapered portion.

What I claim is:

1. A firecracker having a truncated tubular tapered body portion of substantially uniform thickness throughout its length, a charge of explosive matter securely wedged within the tapered'body portion at a point between its ends. v

2. A firecracker having a truncated tubular tapered body portion of substantially uniform thickness throughout its length, a charge of explosive matter securely wedged within the tapered body portion at a point between its ends, the explosive matter being enclosed in a bag.

In testimony whereof I affix my signature.
